Hi. Hair fall if more then a 100 strands a day is what we consider as a problem. Many reasons exist for such kind of hair fall which should be meticulously noted after a detailed history. Along with some important tests which could give us an idea as to the ideal cause. Some important things in the history include any stress, febrile states, infections, thyroid, crash dieting etc. Regarding the itchy palms, it should be properly examined by a dermatologist.
